Description
For font features/languages, I ran into an issue in that the Text object is only supplied to Renderer.draw_text if the string is not multiline:
matplotlib/lib/matplotlib/text.py
Line 805 in b4cb934
I tried a small change:

renderer.close_group('text')AFAICT, only the PGF backend uses mtext and under certain conditions will place the text using the original position and alignment instead of the x/y passed to draw_text. Unfortunately, these don't seem to match (I assume the x/y passed in accounts for the descenders and other flourishes), so this breaks the PGF tests. I wonder if there's a better condition to be put in here:
matplotlib/lib/matplotlib/backends/backend_pgf.py
